Out of the following, select those that would help to reduce water pol...
Explanation:
The correct answer is option 'C' which includes (i) and (iv).
Reasoning:
Water pollution refers to the contamination of water bodies such as rivers, lakes, oceans, and groundwater, which can have detrimental effects on the environment and human health. To reduce water pollution, it is important to implement measures that prevent the introduction of pollutants into water bodies. Let's analyze each option:
(i) Use of sewers for removal of urban waste:
Using sewers for the removal of urban waste is an effective method to prevent water pollution. Sewers collect and transport wastewater from urban areas to treatment plants where it is treated before being released back into the environment. This helps to remove pollutants and harmful substances from the wastewater, reducing the chances of water pollution.
(ii) Use of unleaded petrol in cars:
While the use of unleaded petrol in cars helps to reduce air pollution by decreasing the emission of harmful pollutants, it does not directly contribute to the reduction of water pollution. Therefore, this option is not correct.
(iii) Spraying of pesticides on plants:
Spraying pesticides on plants can actually contribute to water pollution. When pesticides are sprayed on plants, they can run off into nearby water bodies, contaminating the water and harming aquatic life. Therefore, this option does not help to reduce water pollution.
(iv) We should not excrete in the open:
Not excreting in the open is an important measure to prevent water pollution. When human waste is not properly disposed of, it can contaminate water sources and spread diseases. By using proper sanitation facilities such as toilets and sewage systems, the risk of water pollution can be significantly reduced.
Based on the above analysis, options (i) and (iv) are the correct choices as they both contribute to the reduction of water pollution. Therefore, option 'C' is the correct answer.
